The reason Capcom is aiming to cut down development time is because it wants to have more major releases each year in an effort to combat falling sales and earnings. Currently, according to Nikkei, Capcom releases a couple of major titles each year. It hopes to increase this output to three or four titles.
As for the external development talent, the company plans on focusing on North American and European studios. We can see this in practice already with one of Capcom's big upcoming releases, Dead Rising 2.
